The root cause of common failures that cause the marking effect of laser marking machines to not be leveled? The use of laser marking machines is very common, especially in the field of craft products.favored, many customers rely on laser CNC engraving machines to make the first bucket of gold in laser cleaning machine manufacturers, and they have started and become rich.

But equipment is also like people. With the increase of use time and damage to parts, various problems will occur to equipment. The same is true for laser CNC engraving machines, which are likely to cause unfair cleaning of the bottom end.

So, what actually caused the CNC engraving machine to have the common failure to clean up uneven bottom? How should I solve it myself? Today, I have sorted out the following materials for everyone's reference.

Failure to flatten the marking effect of laser marking machines is one of the common problems. It is mainly manifested as a significant protrusion at the bottom end during cleaning, and a significant marking effect at the horizontal and vertical junction during negative engraving. When carving, there is a significant raised vertical line between the words and the words. The heavier the marking, the more significant the phenomenon.

The causes of the problem causing the uneven marking effect are as follows:

1. The laser switching power supply emits unstable light.

2. The production and processing rate is too fast, and the response time of the laser tube cannot keep up.

3. The optical path is deviated or the focal length is incorrect, causing transmitted light and uneven bottom.

4. The selection of focusing lenses is not scientific. Short-focus eyeglass lenses should be selected as much as possible to improve light quality.

The solution for cleaning without leveling the marking effect is as follows:

1. Remove and replace the laser switch power supply test.

2. Reduce production and processing rates.

3. Check the light path to ensure that the light path is appropriate.

4. Using short focus lens, the focus adjustment should take into account the deep layer being produced and processed
